CARPET- LINING.

SPECIFICATION forming part of Letters Patent: No. 269,039, dated December 12, 1882.

Application tiled June 1, 1882. (No model.) l

To all whom it may concern Be it known that I, FRANCIS P. FRENCH, of Denver, in the county of Arapahoe, andin the State of Colorado, have invented an Improvement-in Carpet-Linings; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to paperllinings for earpets; and it consists in certain peculiarities of constructiomall as more particularly set forth hereinafter.

In the drawings, Figure l is a perspective view of a portion of one of my improved carpetlinings. -Fig. 2 is asection of the same. Figs. 3 and 4 are perspective views of modified forms of my said linings. All of these views repre sent the linings upside down, or the reverse from their position when in use, the betterl to illustrate their construction.

A A represent sections of the carpet-lining, made of paper or analogous material, and pret'- erablymolded into the shapes shown directly from the pulp.

c a are small holes or pert'orations (which or any other shape preferred) to admit the ot' the lining. t l

b represent the thickest portions of my lining, while cc designate the spaces between these'thick portions on the under side ot' the lining, which spaces are produced by making the lining ot' only about half the thickness at these places that it is at b b. This, as intimated,can be most easily effected by molding the lining entire directly from the paper-pulp; but it is obvious that a similar el'Iect may be` accomplished by making the portions b b scparately and afterward securing them to the under side ofthe main body of thecarpet-lining either by glue or other adhesive substance or hystitching them to place,or by tacks, pins, rivets, or other' well-known means 'ot' attachment; but I prefer to have my lining all in one solid piece, as it can thus be more cheaply made, besides being neater in appearance and more durable than when made in many pieces and afterward united together. rIhe spaces c between the portions b may be of any desired width ,from the narrow grooves 4shown in Figs. l and 2 to the wide channels Vwill present a smooth surface (perforated at intervals) for the reception ofthe carpet. The dust in the latter, instead of settling between the lining and the carpet,as with the old solid linings, will sift through the described perforations and lodge in the spaces c between the door and lining, while the walls ot' the thick portions b will keep it in place and prevent its rising again whe-n the carpet is next swept, besides which, by reason of its final lodgment in the described spaces, all uneveuness of the 'lining is preventethas might otherwise occur,

it' the-lining were simply perforated, without the spaces c, which nnevenness has been an objection to perforated carpetlinings hitherto used. My lining thus not only, by its perfect evenness, prevents undue wear of the carpet, but also enables a carpet to be swept without raising clouds ot' dust, which is the great objectionto carpets laid upon the ordinary linings now in uw.

Having thus described my invention, what I claim as new, and desire to secure by Letters I Patent, is-

A carpet-lining having abody of unequal thickness and presenting a smooth upper snrt'ace, provided with pert'orations at intervals for the transmission of dust, the thinner portions ot' theliningforming spaces on the under sideforthc reception and retention of the dust transmitted through the described perforations, and the thicker portions being solid or integral with the body ,ot' the said lining, as set forth.

In testimony that I claim the foregoing Il have hereunto set my hand this 10th day of March, 1882.
